Understanding the Accuracy of Our Internal Clock: Circadian Rhythm Explained

Explore how our internal clock regulates bodily functions and factors that influence its accuracy.

280 views

Our internal clock, or circadian rhythm, is fairly accurate but can be influenced by external factors like light exposure, meals, and activities. It roughly follows a 24-hour cycle, helping to regulate sleep, hormone release, and other bodily functions. Keeping a consistent schedule for sleep and meals can help maintain its accuracy. However, disruptions like travel across time zones or irregular work hours can cause it to drift.
